RESUMO

Background: Fragile X Syndrome (FXS) is the second cause of Mental Retardation (MR) and the first cause of familiar MR. This syndrome affects up to 1/4000 men and 1/8000 women. X syndrome is often diagnosed by molecular biology technique such as RCR and Southern blot. Until now there is no study on FXS in Vietnam. Objectives: This study is aimed at: (1) Determine FXS among children with MR by technique of molecular biology. (2) Determine the mutation of FMR1 gen in families having children with FXS. Subject and Method: 214 children between 6 and 16 years of age (136 male and 78 female) with MR were analyzed FMR1 gen by PCR and Southern blot techniques. Families of children with FXS were also analyzed. Result and conclusion: This is the first study on FXS using the techniques of molecular biology in Vietnam. Identified 3 children with FXS, accounting for 1.4% of MR. Children with FXS and members with full mutation and premutation were found.

RESUMO

Background: Mental retardation is a common pathological state in children, accounting for about 1 - 3%. Children with mental retardation should have a life of integrity and proper support. The discovery and assessment the children will help us to orient the education, assistance and early intervention for them at each location. Objectives: This study aimed at determining the prevalence of mental retardation (MR) among children in some quarters and communes of Hue city and the degrees of mental retardation in these children. Subjects and method: Screening by WHO questionnaire \u201cTen Question screen for disability\ufffd?and learning results (if possible) of children from 6 to under 16 years old in 5 quarters (urban) and 2 communes (rural) randomly selected in Hue. Diagnostics and evaluations are based on the criteria of ICD \ufffd?10. Results: The prevalence of MR in this study was 0.94% (95%CI = 0.82 \ufffd?1.07), 1.18% in rural area and 0.84% in urban area; 1.16% among boys and 0.70% among girls. Mild MR accounts for 62.67% moderate: 19.36%, severe: 11.52% and profound: 6.45%. Conclusion: The prevalence was statistically significant higher in rural area than in urban area and in boys than in girls. There were predominant percentages of severe and profound MR.
